Abstract
One of the main priorities among European Union member states is to promote
renewable energy. Latvia also has to comply with the European Parliament and
Council Directive 2009/28/EC on the promotion of renewable energy initiated on
23 April 2009. The directive states that the share of renewable energy has to
reach 40 % of total final energy consumption by 2020. Part of this share can be
achieved with the energy produced by burning biogas in cogeneration plants.
Each domestic activity generates an environmental impact. Before the activity
commences, the potential impact of activities has to be assessed. One of the tools
that is widely used and is included in the Latvian legislation is the Environmental
Impact Assessment (EIA). Environmental impact assessments are applied to
different objects, where there is a risk that the construction or operation may
have a negative impact on the environment, as well as on human health.
According to Latvian legislation, the activities, depending on their potential
impact, are divided into two parts: the activities for which an EIA has to be
completed and activities for which a screening has to be performed. The aim of
the screening is to evaluate whether the activities can cause significant effects on
the environment. Solely on the basis of the results of the screening a decision is
made whether to perform the EIA procedure or not. The definition of the
significance of the impact is essential. The defined criteria in the European
Union legislation are included in the legislation of Latvia. The criteria specify
the minimum range of points to be covered during the screening.
Biogas production through anaerobic digestion is considered as one of the
most successful methods of dealing with increasing environmental pollution.
Heat and electricity are produced by burning biogas in cogeneration plants. A
wide variety of inputs can be used to produce biogas: livestock manure, crop
