Science based targets

What are science-based targets and how can companies adopt them?

The Intergovernmental Panel on Climate Change (IPCC) revealed that the impacts of climate change are already widespread. Anthropogenic GHG emissions are responsible for climate change and global warming. IPCC identified the world’s “carbon budget”, which is the total volume of GHGs that can be emitted while providing a degree of confidence that temperature rise will…

Scientist Discover a New Method to curb greenhouse gases

Scientists discovered a new method to convert harmful Greenhouse Gases (GHGs) into chemicals which can produce synthetic fuels on 2 February 2014. A team of researchers at the University of Delaware has developed a highly selective catalyst capable of electrochemically converting carbon dioxide (a greenhouse gas) to carbon monoxide with 92 percent efficiency. The carbon…

Leaked UN Report Says Level of Greenhouse Gases Rising Rapidly

Leaked draft IPCC UN report on 17 January 2014 has warned about rise of the level of greenhouse gases and it calls for greater global efforts to tackle the issue. The Intergovernmental Panel on Climate Change (IPCC) report has also mentioned that if the current situation continues that hugely expensive technology will be required. The…

European Union Parliament approves CO2 emission restrictions for commercial vans

The Parliament of Europe approved new carbon dioxide restrictions for commercial vans on 14 January 2014. The move is expected to bring down emissions by 28 percent from 2020. Under the new rules, all new light commercial vehicles sold across the European Union (EU) will emit a maximum 147 g of carbon dioxide per kilometer…

New greenhouse gas with highest global warming impact discovered

A new discovery by scientists has revealed a new greenhouse gas that appears to have the highest global-warming impact. Perfluorotributylamine (PFTBA) – discovered by Toronto’s Department of Chemistry research team concluded that the compound is most effective in potential to harm the climate, in a study published in the journal Geophysical Research Letters. Carbon dioxide…

How to calculate GHG emission for electricity consumption from the grid?

A large portion of Greenhouse Gas emissions (GHG) from most companies comprise of consumption of electricity from the grid. In India, around 65% of electricity is coming from coal and other fossil fuel based thermal power plants. Electricity generated from these power plants contributes in GHG emissions. Therefore, electricity being consumed from the grid also…

To achieve GHG emission reduction target, Wipro Ltd is sourcing renewable energy to minimize its scope 2 emission (GHG emission from the consumption of purchased electricity). In 2012-13, energy efficiency measures taken by Wipro Ltd have contributed to a 5 % decrease in energy intensity per employee. This is due to the installation of automatic timers and switches that help reduce unnecessary energy usage by chillers, lights, and elevators. One of the major achievements by Wipro Ltd in FY 2013 is increased share of renewable energy from 17% to 19% of the total office energy consumption. In this period, Wipro Ltd procured 63 Million units of renewable energy through power purchase Agreements with private renewable energy generators, which is approximately 19% of Wipro’s total office space energy consumption in the IT business. Wipro has in turn identified three key elements for GHG emission reduction. These are energy efficiency in existing operations, purchasing renewable energy and renewable energy generation. As per the annual report of Wipro, a total 85% of GHG emission reduction target of Wipro will be achieved through use of renewable energy. Reference: Wipro 2012-13 Annual report

Greenhouse Gas Management at Wipro Ltd

Carbon dioxide is one of the six Greenhouse gases (GHG) that causes climate change. Therefore it is important to reduce GHG emissions of CO2. Carbon dioxide emission reduction is important to develop an environment friendly identity of an organization. Many organizations have developed carbon accounting and management system to take benefits from it. Some of…

How do Municipal Solid Waste Disposal Sites Emit Methane?

Municipal Solid Waste is the waste material typically discarded by households comprisingdry & wet waste materials. Solid waste is a significant contributor to the greenhouse gas (GHG) emissions through decomposition /anaerobic digestion. Anaerobic digestion (AD) is the process by which organic materials in the waste are broken down by micro-organisms in the absence of oxygen….
