Diesel Engines & Public Health
Diesel-powered transportation sources in the US are responsible for over 60 percent of nitrogen oxides (NOx) and more than 70 percent of fine particulate matter (PM2.5) emissions. The World Health Organization classifies diesel exhaust as carcinogenic, with components like PM2.5 and NOx causing respiratory and cardiovascular illnesses, premature death, and reduced lung function. These health impacts disproportionately affect communities of color and socioeconomically disadvantaged populations. While over 100 models of electric trucks and buses are currently available, the document argues that public policy is necessary to accelerate the market and address the climate crisis and health disparities.

GAS FLARING IN NIGERIA: A HUMAN RIGHTS, ENVIRONMENTAL AND ECONOMIC MONSTROSITY
Nigeria is identified as the world's largest gas flarer, wasting approximately 2.5 billion cubic feet of associated gas daily, which results in an annual economic loss of US $2.5 billion. The report asserts that flaring has been generally illegal since 1984 under the Associated Gas Reinjection Act, yet continues through a lack of transparency regarding ministerial certificates. Environmental impacts include the emission of roughly 70 million metric tons of CO2 annually and the creation of acid rain that corrodes infrastructure. Health risks for local communities, specifically in Bayelsa State, include increased rates of premature death, child respiratory illnesses, asthma, and cancer due to exposure to particulate matter and benzene. The report criticizes the 'double standards' of the British colonial legacy and the failure of projects like Bonny LNG and the West African Gas Pipeline to prioritize the use of associated gas over non-associated gas.

Agency Experts Aghast: EPA Adjusts Air Quality Models
In April 2004, air quality modelers from nine EPA regional offices protested a policy change allowing states to select their own baseline years for measuring pollution in 'Class I' areas. This policy emerged from a compromise with North Dakota, which had been out of compliance with the Clean Air Act regarding Theodore Roosevelt National Park, hindering plans for new coal-fired power plants. EPA scientists argued the change 'artificially inflate[s]' baselines to mask policy changes and feared it would set a national precedent, as other states like Colorado, Montana, South Dakota, Utah, and Wyoming sought to follow suit.

The Full Costs of Thermal Power Production in Eastern Canada
The report applies a full cost accounting (FCA) approach to quantify the externalities of thermal power production in Eastern Canada, focusing on air pollution (SOx, NOx, VOC) and greenhouse gas (GHG) emissions. It finds that coal-fired power generates the highest externalities, with central estimates of $0.0394/kWh, which exceeds its marginal production cost of approximately $0.026/kWh. The study argues that internalizing these costs would shift investment toward natural gas, demand-side management, and renewable energy, and warns that Canada's Kyoto compliance strategy may forego domestic health co-benefits by favoring international emission credits over domestic reductions.
