The policy brief asserts that global climate success depends on the 20 largest emitting nations adopting a small set of high-impact policies across four sectors: electricity, buildings, industry, and transportation. It emphasizes that policy design is critical to avoid inefficiencies and suggests the use of 'Best Practice Networks' (BPNs) to provide technical expertise to governments to ensure these policies are effectively implemented.

The document provides a synthesis of challenges and lessons learned from the preparation of intended nationally determined contributions (INDCs) by UNFCCC Parties prior to the Paris Agreement. It aims to support the implementation and development of nationally determined contributions (NDCs) by improving clarity and ambition. The findings are based on NewClimate Institute research, including two surveys of developing country representatives, and incorporate examples from GIZ's work with over 30 partner countries to address thematic challenges.

A statement from the We Mean Business Coalition calling for the UK government to establish a legal net-zero emissions goal, noting that participating companies have set their own targets to ensure long-term sustainability and profitability.

The report examines how to reform EU energy law to meet 2030 targets, specifically a binding EU-wide target of 27% renewable energy and a 27% energy savings goal. It identifies four primary areas for streamlining: the alignment of renewable energy and energy efficiency targets, the merging of planning and reporting requirements, the consolidation of building-sector provisions into a single directive, and the transfer of market-barrier removal provisions to a reviewed internal electricity market directive. The authors argue that synchronizing these amendments during the 2016 legislative review period would reduce administrative burdens, enhance policy coherence, and increase investor certainty.

The report finds that 70% of Americans believe global warming is happening, though only 53% believe it is mostly human-caused and 11% are aware of the strong scientific consensus. While 58% express worry, few are 'very worried,' and many perceive the threat as distant, though perceptions of immediate harm in the U.S. have reached a record high of 38%. There is strong public support for corporate and individual action, as well as for teaching climate change in schools, but low confidence in the U.S. Congress's ability to pass necessary legislation.

The Supreme Court suspended the Clean Power Plan, which sets CO2 limits on coal-fired power plants, following a lawsuit by a coalition of states and corporations. Despite this legal action, 61% of adults across the 27 suing states support the policy, with majorities in 23 of those states favoring strict carbon dioxide emission limits to combat global warming and improve public health.

The Obama Administration set a goal to reduce methane emissions from the oil and gas sector by 40-45% from 2012 levels by 2025. While the EPA proposed standards for new and modified sources, it has failed to address existing sources, which a 2014 ICF International study predicts will represent 90% of the sector's total methane emissions in 2018. Analysis by CATF and the Rhodium Group indicates that voluntary industry programs are insufficient to bridge the 'methane emissions gap', as even 100% participation would leave a gap of 54 million metric tons of CO2e. The author asserts that nationwide standards on existing oil and gas equipment would reduce emissions by 77 million metric tons of CO2e, sufficient to meet the Administration's goal.

The report identifies a 'methane emission gap' between the Obama Administration's goal to reduce oil and gas methane pollution by 40–45% from 2012 levels by 2025 and the actual impact of its proposed regulations. It finds that proposed standards primarily target new and modified sources, while existing sources are projected to represent 90% of the sector's total methane emissions in 2018. To close the gap of at least 75 million metric tons CO2e, the report recommends requiring leak detection and repair, non-emitting pneumatic technologies, and the capture of gas from oil wells for existing sources.

The document examines the intersection of science and urban policy, identifying that while research can provide robust data to validate decision-making and increase citizen trust, significant gaps exist due to differing timeframes, technical languages, and motivations. It argues that co-creating solutions and bridging the gap between researchers and practitioners is essential for the successful implementation of the Basque Declaration's sustainability goals.

The report finds a deep partisan divide in climate perceptions, with supporters of Democratic candidates (Sanders and Clinton) and some Republican candidates (Kasich and Trump) generally believing global warming is happening, while Ted Cruz supporters are the most skeptical. While a broad majority of voters support renewable energy research and tax rebates for energy efficiency, support for carbon taxes and strict emission limits on coal plants drops significantly among Republican supporters, particularly those of Ted Cruz. Global warming is viewed as a very important voting issue primarily by Sanders and Clinton supporters, whereas it ranks low for supporters of Republican candidates.

The report finds that while 73% of registered US voters believe global warming is happening, there is a significant divide between conservative Republicans and other political groups. Most voters support clean energy research and carbon regulation, and are more likely to vote for a presidential candidate who supports climate action than one who opposes it.

The report reveals a deep partisan divide in climate change perceptions. Supporters of Democratic candidates (Sanders, Clinton) and some Republican candidates (Kasich, Trump) generally believe global warming is happening, whereas a majority of Ted Cruz supporters do not. While there is broad support across most candidate groups for renewable energy research and tax rebates for energy-efficient products, significant gaps exist regarding carbon taxes, CO2 regulation, and the importance of climate change as a voting issue.

The report finds that while a majority of US registered voters believe global warming is happening and support various clean energy policies, significant ideological divides persist. Democrats and liberal/moderate Republicans generally align with the mainstream public in supporting climate action, whereas conservative Republicans remain the most skeptical group, though they have shown the largest increase in belief that global warming is occurring over a two-year period. Public awareness of the scientific consensus on human-caused warming remains very low across all political groups.

The report examines how stakeholders in Swedish forestry perceive climate change risks and opportunities. It finds that while some anticipate increased growth, others fear storm damage and pests. Adaptation is driven by personal experience of extreme weather and trust in advisers, but hindered by distrust of climate science and conflicting views on effective management strategies. The document emphasizes the need for user-oriented, interactive communication between researchers and practitioners to foster adaptation.

The document clarifies that the outcome of the Paris climate talks will likely be a 'package' of instruments with varying legal forms, including a core legal agreement, UNFCCC decisions, and potential political declarations. It emphasizes that the legal force of the agreement is determined by its specific content and prescriptive language rather than its name (e.g., treaty, protocol, or accord). The text further explains that the agreement can contain a mix of binding and non-binding provisions and that the domestic ratification processes of participating countries will vary according to their own legal systems.

The We Mean Business Coalition argues that current Intended Nationally Determined Contributions (INDCs) from over 180 countries are insufficient, potentially leading to 2.7°C of warming. To bridge this gap, the author proposes a formal mechanism within the Paris Agreement—specifically referencing Articles 3 and 10—that requires countries to communicate and strengthen their climate commitments every five years starting from 2020. The document warns that a failure to update policy environments every five years will cause government progress to lag behind businesses and investors, increasing risks for the private sector.

A survey of 1,330 American adults conducted in 2015 shows strong public support for an international climate agreement in Paris, with 71% stating such an agreement is important. A majority of respondents (64%) believe the U.S. should do more to address global warming, and 62% argue the U.S. should reduce emissions regardless of the actions of other countries. Furthermore, majorities believe both developing countries (72%) and other industrialized nations (66%) should increase their efforts to combat climate change.

The guide outlines three primary strategies for business engagement during COP21: educating leaders on climate science and policy, making public climate commitments through platforms like the Lima-Paris Action Agenda and the We Mean Business 'Take Action' campaign, and participating in onsite networking and events in Paris. It highlights specific tools for tracking commitments, such as NAZCA, and lists various side events and hubs, including the 'Open to Business' hub, designed to facilitate business-led climate action.

Earthjustice condemns the U.S. Senate's vote on S.J. Res. 24, which sought to repeal the Clean Power Plan, describing the plan as the most significant U.S. action on climate change to date. The organization notes that the President intended to veto the resolution and highlights the contrast between the Senate's action and the efforts of world leaders to address climate change in Paris.
