Reduction of carbon dioxide emissions

One of the important challenges facing companies that engage in policies of sustainable development is the containment of greenhouse gas emissions, particularly CO2, given the massive and inherent production of the gas through fossil fuel consumption.

The Paris Protocol of February 2015 – A blueprint for tackling global climate change beyond 2020, states: “According to the latest findings of the Intergovernmental Panel on Climate Change (IPCC), without urgent action, climate change will bring severe, pervasive and irreversible impacts on all the world’s people and ecosystems. Limiting dangerous rises in global average temperature to below 2°C compared with pre-industrial levels (the below 2°C objective) will require substantial and sustained reductions in greenhouse gas emissions by all countries.”

For a number of years, Acea has followed a policy of containment of CO2 emissions. In keeping with this, the company participates in the international Carbon Disclosure Project (CDP). The Group joined the project was in 2004, considering it a stimulus to rigour and methodology in the reduction and mitigation of emissions, and for diffusion of awareness on the issue. The declaration of the industrial processes and quantities of CO2 in play permits the Group to respond to the challenges of industrial management with low or “zero” rates of CO2 emissions.

Over the past 10 years, Acea has undertaken initiatives such as the use and production of green energy, increase in efficiency of internal uses of energy, and modernisation of its vehicle fleet. With this, Acea has reached one of the lowest values of CO2 intensity (CO2/euro billed) in the Italian utilities sector (see in-depth box).


In December 2014, at Lima, 195 nations completed the negotiations for the final document of UN Climate Change Conference. The text calls on the governments to provide “quantifiable and equitable” undertakings for the reduction of emissions. It serves as the basis for the upcoming Paris Conference, scheduled for December 2015, which is expected to ratify a new binding accord applicable to all parties, as successor to the previous Kyoto accord.

Climate experts will evaluate the impact of the measures identified under the Lima accord, to ensure that they are sufficient to hold the increment in global temperatures to less than 2° C (“below 2°C objective”).

The Lima document was declared approved, after two weeks of negations, by the Meeting Chair, Peru’s State Minister for the Environment, Manuel Pulgar Vidal, before the plenary assembly of delegates.



The 9th edition of CDP 100 2014 Italy Climate Change Report was presented on 05/11/2014 at the Milan seat of the Borsa Italiana. The report is prepared by international experts, and provides an evaluation on climate change topics, elaborated from information provided by around 100 Italian companies participating in the “Carbon Disclosure Project”.

The report provides a ranking in terms of the transparency of communications on corporate practices against climate change (“disclosure”, rated from 0-100), and the company’s demonstrated results in containing the carbon footprint in its relevant activities (“performance” – rated D-A).

Acea is a long-standing participant in the Carbon Disclosure Project. Once again, the company improved its rating, going from an overall score of 88B in 2013 to a rating of 92B in 2014.

In the utilities sector, which includes nine companies, Acea ranked third from the top, after Enel and Snam, and was noted in particular for its policies on containing CO2 emissions.
