Misinformation Alert: Heat Pumps
The document outlines how heat pumps are targeted by 'Cost of Net Zero' misinformation, which portrays them as expensive, inefficient, and unsuitable for certain homes. It provides factual rebuttals—such as the potential for £340 savings when replacing G-rated boilers and the ability of pumps to operate at -25 degrees—and advises communicators to use positive case studies and avoid social media algorithms to reach 'Persuadables'.

CATF Response to UK consultation on hydrogen blending into GB gas distribution networks
CATF opposes the UK government's consultation on hydrogen blending into gas networks, stating that low-carbon hydrogen is too scarce and expensive to be used for residential heating or minimal GHG reductions in power generation. They recommend prioritising 'no regrets' industrial sectors, such as refineries and ammonia producers, and using electrolytic hydrogen from curtailed electricity for long-duration energy storage instead of grid injection.

Electrification Data Methodology 2024 Overview
The 2024 Electrification Data Methodology describes how Ember calculates the energy and emissions impacts of electric vehicles (EVs) and residential heat pumps. The methodology focuses on operational energy use, calculating the 'displaced' primary fossil fuel consumption and CO2 emissions by comparing the energy required for electrification technologies against the fossil fuel alternatives they replace. For transport, the model accounts for vehicle stocks, mileage decay, and charging losses. For residential heating, it utilizes final energy consumption data, boiler efficiency factors, and seasonal coefficients of performance (SCOP). The analysis covers the European Union and the United Kingdom, utilizing data from sources such as Eurostat, the IEA, and the UK Department for Transport.

Heat pumps are hot in the Maritimes
The report examines the 'Maritimes anomaly,' where New Brunswick, Nova Scotia, and Prince Edward Island have achieved significantly higher heat pump adoption rates than the rest of Canada. It attributes this success to a combination of high energy poverty, a moderate Atlantic climate, existing institutional commitments to energy efficiency, and aggressive financial incentives. The document highlights the importance of 'stacking' provincial and federal grants and warns against the rise of unreliable installers.

Les thermopompes en vogue dans les Maritimes
The report analyzes why New Brunswick, Nova Scotia, and Prince Edward Island have seen a surge in heat pump installations compared to the rest of Canada. It attributes this 'anomaly' to a combination of moderate climates, high energy poverty, existing electrical infrastructure, and aggressive financial incentives. The study highlights the role of established energy efficiency agencies and the effectiveness of combining heat pump rebates with broader home energy audits. It also notes challenges such as unreliable installers and administrative bottlenecks, offering lessons for scaling electrification across Canada.

Hydrogen heating is the next energy crisis in the making
Global Witness contends that hydrogen heating is an inefficient and dangerous alternative to heat pumps, pushed by gas companies to avoid stranded assets. The briefing criticizes the UK Energy Bill for introducing a hydrogen levy on consumers and proposing forced participation in heating trials in locations like Redcar or Whitby, Ellesmere Port.

Mini-grid/off-grid Solution for Ger Area
XacBank LLC is seeking USD 914,425 from the Green Climate Fund to prepare a comprehensive funding proposal for a mini-grid system in Ulaanbaatar's ger areas. The project aims to address air pollution and utility inadequacies caused by coal-based heating and lack of sanitation. The requested PPF funding will support technical feasibility studies, financial and legal structuring, environmental and social impact assessments, and market analysis over a 14-month period.

Bridging Transition Pathways
The paper argues that existing transition models are often either purely quantitative or purely social, lacking a holistic view. By bridging an energy systems model with socio-technical analysis and local action studies, the authors aim to create a more realistic picture of the transition to a low-carbon residential heating system by 2050. The framework integrates niche innovations as scenario options, landscape signals as external drivers, and regime studies to identify governance barriers, while local action studies provide data on community attitudes.

Coal transition in Poland
The report analyzes the necessity of transitioning Poland's coal-dependent energy system to meet global climate goals. It compares a 'baseline' business-as-usual scenario with a '<2°C-consistent' scenario, the latter requiring a 67% reduction in per capita CO2 emissions by 2050. The analysis highlights that while the power sector must shift toward renewables and nuclear energy, the transition's social viability depends on managing the decline of the mining sector—particularly in the Śląskie region—through natural attrition, retraining, and conditional financial support to avoid the social exclusion seen in previous regional closures.

ENERGY SAVINGS FROM WINDOW SHADES
The report evaluates the energy impact of Hunter Douglas insulating honeycomb shades using whole-building simulations in nine U.S. cities. It finds that these shades can significantly reduce heating and cooling energy consumption, particularly in existing homes, while improving operative temperatures and reducing peak electrical demand. The study emphasizes that savings are highly dependent on the operation schedule and window orientation, with west-facing windows being critical for peak demand reduction in summer.

Time To Confront A Major Climate Pollutant: Soot
The document highlights the significant role of black carbon (soot) as a short-lived climate forcer that accelerates warming and melting in the Arctic by darkening ice and snow. It calls on environmental ministers of Arctic nations to lead efforts in reducing these emissions, noting that black carbon is now identified as the second most important climate pollutant with twice the climate impact previously understood.

Long Run Demand for Energy Services: the Role of Economic and Technological Development
The research analyzes energy service demand in the UK over two hundred years, finding that income and price elasticities generally follow inverse U-shape and U-shape curves respectively as economies develop. However, these trends are frequently disrupted by technological transitions that introduce new value attributes or expand market access to poorer populations, often leading to rebound effects where efficiency gains increase overall energy consumption. The author concludes that energy demand in developing economies is likely to continue rising rapidly, and in industrialized nations it is unlikely to decline, suggesting long-term increases in global carbon dioxide emissions unless a full transition to low-carbon technologies occurs.

Understanding Interstate Differences in U.S. Greenhouse Gas Emissions
The paper analyzes the drivers of per capita CO2 emissions across U.S. states, noting a wide range from 76.5 mT in Alaska to 12.2 mT in Vermont. It identifies that high transportation emissions are linked to sparse populations, low gasoline prices, and limited public transit. High residential heating emissions are associated with cold climates, high average incomes, and the use of oil for heating. Additionally, high residential electricity emissions are driven by coal-based power generation, hot and humid climates, and low electricity prices. The authors highlight gasoline prices, electricity prices, and public transportation use as key policy variables.

Greening The Greys
The report finds that UK baby boomers (50-64) have the highest carbon footprint due to high spending on travel and consumption, while the oldest group (75+) has the highest climate impact per pound spent, primarily due to home heating. Despite general fear and motivation to act, older adults face barriers such as the cost of public transport and high capital costs for home energy efficiency.

The Last Climate Frontier: Leveraging the Arctic Council to make Progress on Black Carbon and Methane
The report argues that the Arctic is warming twice as fast as lower latitudes, with black carbon and methane having a disproportionate impact. It proposes that the U.S., during its 2015-2017 Arctic Council Chairmanship, should champion best practices in the oil and gas sector, advocate for a heavy fuel oil ban in shipping, promote clean energy for residential heating, and implement strategies to curb open burning.
