A group of 22 global business and civil society leaders is calling for a net-zero greenhouse-gas emissions goal by 2050 to be established at COP21. They argue that such a goal is necessary to mobilize private sector investment, innovate for global decarbonization, and protect the Sustainable Development Goals. To demonstrate feasibility, several signatory companies, including Unilever, Salesforce, and Virgin Group, have already committed to achieving net-zero emissions by 2050 within their own operations.

The We Mean Business coalition asserts that the economic case for climate action is now clear, with 200 international companies and over 100 investors already making ambitious commitments. The coalition calls for a Paris Agreement that ensures global decarbonization by the end of the century, establishes five-year update cycles for government commitments, and provides clear policy signals like carbon pricing to shift investment toward low-carbon assets.

The We Mean Business coalition asserts that the Paris Agreement must establish a collective long-term goal of net zero greenhouse gas emissions well before the end of the century to keep warming below 2°C. The authors call for mechanisms to regularly strengthen country commitments every five years, implement transparent government accountability rules, and shift trillions of dollars toward low-carbon investment through policy signals like carbon pricing.

The B Team calls for a global net zero greenhouse gas emissions target by 2050 to be codified in the Paris climate agreement, arguing that such a clear market signal would drive investment in low-carbon infrastructure and renewable energy while mitigating catastrophic economic and environmental risks.

The We Mean Business Coalition advocates for a global climate agreement that limits temperature rises to below 2C, emphasizing the need for a net-zero emissions goal, scalable climate finance, and increased short-term ambition through the UNFCCC Workstream 2. The coalition argues that bold climate action represents a historic economic opportunity, noting that some low-carbon investments have achieved an internal rate of return (IRR) of 27%.

Richard Branson and B Team leaders advocate for a global commitment to net-zero greenhouse-gas emissions by 2050, arguing that this target is necessary to avoid the most catastrophic consequences of climate change. The statement calls for a meaningful price on carbon and the redirection of fossil fuel subsidies toward renewables, emphasizing that bold government commitments in Paris will drive business innovation and investment.

The paper proposes four complementary mechanisms to enhance the UNFCCC's effectiveness for the 2015 agreement: specifying a global long-term emissions goal (such as net zero by mid-century), establishing a predictable commitment cycle for national contributions, ensuring each cycle results in increased emissions reductions, and implementing an assessment and revision process to identify further low-carbon policies.

The ACT 2015 consortium proposes five key ingredients for a successful 2015 global climate agreement: a clear long-term goal (including net zero by 2050), a commitment to non-regression of national targets, a five-year cycle for strengthening commitments, the integration of independent expert analysis, and a transparent progress assessment mechanism.

The World Resources Institute (WRI) reported total CO2 emissions of 1,125 metric tons in 2006 and 1,288 metric tons in 2007, representing increases of 6% and 21% respectively over its 2000 base year. These increases are attributed to a 33% growth in staff and the expansion of office space in Washington, DC. To maintain a "net zero" balance, WRI utilized the Chicago Climate Exchange for 2006 offsets and transitioned to Certified Emission Reductions (CERs) under the Kyoto Protocol's Clean Development Mechanism for 2007, sourcing credits from wind and landfill gas projects in India and China. Management activities included achieving LEED Gold Certification for office expansion and planning a 3,600-square-foot green roof. WRI also utilized Renewable Energy Certificates (RECs) to cover 100% of its 2007 electricity use, though it maintained a conservative accounting approach by purchasing offsets for all reported emissions regardless of REC value.

The World Resources Institute (WRI) reported 'net' CO2 emissions of 1,031 metric tons in 2004 and 978 metric tons in 2005, representing a 3% and 8% decrease respectively from its 2000 base year. To achieve its 'net zero' goal, WRI utilizes a combination of internal efficiency measures, the purchase of renewable energy certificates (RECs), and investments in GHG offsets through the Chicago Climate Exchange. The organization also updated its accounting methodology to exclude paper emissions from its primary goal due to calculation uncertainties, though it continues to track them separately. Beyond its own footprint, WRI manages several multi-stakeholder partnerships, including the GHG Protocol and Climate Northeast, to promote corporate greenhouse gas management.

The report identifies a resurgence of climate denial and the rise of 'delayism' during COP27, highlighting how fossil fuel-linked entities used Meta's advertising tools for greenwashing and how Twitter's algorithms surfaced the #ClimateScam hashtag despite lower engagement than pro-climate terms. It details a 'narrative playbook' where climate action is framed as an elitist plot or a 'culture war' issue, often overlapping with anti-vaccine and right-wing conspiracy communities.

The report identifies three primary ecosystems driving climate mis- and disinformation: the 'attention economy' of online influencers, state-affiliated networks (specifically Russia), and the fossil fuel lobby. It details how the #ClimateScam hashtag has gained prominence on X, how ad tech companies monetise websites hosting climate denial, how Russian state media instrumentalises climate topics for geopolitical influence, and how fossil fuel companies use Facebook advertising for greenwashing. The document argues that these efforts undermine the public mandate for Net Zero and calls for structural changes to digital platform incentives and greater transparency in ad tech.

The Canadian Association of Physicians for the Environment (CAPE) is calling for a ban on fossil fuel advertising, comparing the industry's deceptive marketing to that of Big Tobacco. The briefing details how fossil fuel emissions cause tens of thousands of premature deaths in Canada, contribute to childhood asthma, and exacerbate climate-related health crises like extreme heat and wildfires. It specifically accuses the Pathways Alliance of misleading the public about emissions and net-zero goals, noting that actual oil sands emissions may be 64 times higher than reported. CAPE advocates for a regulatory framework similar to those implemented in France, Norway, and the EU to protect public health and accelerate the energy transition.

The Canadian Association of Physicians for the Environment calls for British Columbia to update its Building Code and Energy Step Code to prohibit new gas connections by 2022 and set deadlines for existing buildings to switch to clean energy. The briefing highlights that buildings cause 12% of the province's greenhouse gas emissions and that natural gas use contributes to health risks, including childhood asthma from indoor nitrogen dioxide and lung disease linked to hydraulic fracturing in the Peace region. It notes that retrofitting a home from gas to electric currently costs over $20,000, making the 'future-proofing' of new buildings a cost-effective necessity to meet the province's goal of net-zero emissions by 2050.

The Canadian Association of Physicians for the Environment and other health organizations call for a green and just economic recovery from the COVID-19 pandemic. They advocate for investments in renewable energy, sustainable transportation, and nature protection to meet Paris Agreement targets, arguing that such actions would save over 112,000 lives by 2050 and increase clean jobs to 1.5 million. The letter emphasizes the need for a recovery that addresses the disproportionate impacts of climate change and systemic racism on Indigenous Peoples.

A group of doctors and nurses issued a health advisory to the British Columbia government, warning that the expansion of liquefied natural gas (LNG) and hydraulic fracturing (fracking) poses severe risks to public health. They highlight the acceleration of climate change via methane leaks, air pollution causing respiratory and cardiovascular diseases, water depletion and contamination, and adverse community impacts including mental health issues and human rights violations against Indigenous peoples. The advisory calls for a moratorium on new fracking, stricter pollution regulations, an end to natural gas tie-ins in buildings by 2023, and support for workers and Indigenous communities transitioning to a clean-energy economy.

The Canadian Association of Physicians for the Environment (CAPE) and the Canadian Association of Nurses for the Environment (CANE) call for a moratorium on fracking expansion in British Columbia, citing severe health risks to local populations and the climate impact of methane leakage. They recommend a transition to zero-emissions buildings, the end of fossil fuel subsidies, and a just transition for affected workers and Indigenous communities.

The Canadian Association of Physicians for the Environment (CAPE) recommends amending Bill C-12 to include a 2025 emissions target, establish a truly independent scientific advisory body reporting to Parliament, and ensure explicit alignment with the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP). CAPE frames climate change as a critical health threat, noting that Canada is the only G7 country whose emissions have risen since the 2016 Paris Agreement.

The document highlights that just 1% of Argentina's superhot rock geothermal resource could provide 2,659 GW of energy capacity, far exceeding the country's projected 2050 electricity demand of 348,032 GWh. This resource could theoretically replace all fossil fuels used for electricity production, reducing emissions by approximately 47 megatonnes of CO2eq, which represents 129% of Argentina's Nationally Determined Contribution goal. Additionally, the technology offers high energy density, requiring only 12 km² of land per 1 GW, and could eliminate the need for the 17% of natural gas and 4% of electricity that Argentina currently imports.

The document highlights that just 1% of Australia's superhot rock geothermal resource could provide 624 GW of energy capacity, potentially meeting the country's projected 2050 electricity demand of 436,281 GWh. It argues that this technology offers a low-land-footprint alternative to other renewables and a transition pathway for the oil and gas workforce.
