carbon emissions

Leaking tailpipes and wood-fired stoves are some of the culprits that release methane and soot into the atmosphere. Some researchers think cutting these emissions could significantly reduce global warming effects. But a Northwest study has found that it might not reduce effects that much.

A long delayed experiment to demonstrate how a global warming gas can be locked up forever deep underground has finally started. Technicians working with the Pacific Northwest National Lab are injecting carbon dioxide down a well south of Pasco, Wash.

More than a dozen Northwest schools and hospitals have replaced old diesel heating systems with boilers that burn wood pellets. Advocates say that this wood fuel -- called forest biomass -- is an affordable local source of energy. And it can help rural communities cut back on their fossil fuel use.

Governor Jay Inslee made one of his first public appearances since his inauguration at a breakfast for the Capitol Land Trust in Olympia on Tuesday. Several hundred people gathered for the conservation group’s annual breakfast.

A small engineering firm in Seattle says it has developed a system to capture carbon dioxide going up power plant smokestacks and convert it to methanol. The solvent is also known as wood alcohol and as an Indy race car fuel.

Brett Scott is chief counsel for Emission Resource Group. He says having a viable method to refine CO2 into methanol could make it worthwhile for fossil fuel burners to capture the greenhouse gas.

Keeping up with transportation infrastructure isn’t cheap. The Washington State Transportation Commission estimates that in the next 20 years around $200 billion needs to be put towards the maintenance of roads, ferries and more.

University of Oregon researchers say they have found a way to reduce carbon dioxide emissions from coal-burning plants by more than 90 percent. Their formula uses refrigeration to capture and control the dangerous chemicals pumped out of smoke stacks.
